What graph represents the function f(x) = 8 1/3^x?

densk [106]

Answer:

B (second graph from left)

Step-by-step explanation:

The function when x=0 will be 1 since any number to the zero exponent is 1. This means only B and D are options.

Because of the fraction, the values will be smaller and have a gentler slope. B is the solution.

Emma is training for a 10-kilometer race. She wants to beat her last 10-kilometer time, which was 1 hour 10 minutes. Emma has al

Mandarinka [93]

Answer:

$70 > 55 + t$

Step-by-step explanation:

Given

$Previous\ Time = 1\ hr\ 10\ mins$

$Current\ Time = 55\ mins$

Required

Represent the additional time needed as an inequality

Convert the previous time to minutes

$Previous\ Time = 1\ hr\ 10\ mins$

$Previous\ Time = 1 * 60\ mins + 10\ mins$

$Previous\ Time = 60\ mins + 10\ mins$

$Previous\ Time = 70\ mins$

Let the additional time be t

<em>This means that she needs to run at least t minutes to beat her previous record</em>

<em />

To beat her previous record, the sum of current time and x must be less than her previous time. i.e.

$55 + t < 70$

This can be rewritten as:

$70 > 55 + t$

Wendy's restaurant has been recognized for having the fastest average service time among fast food restaurants. In a benchmark s

VikaD [51]

Answer:

(a) 0.2885

(b) 0.0736

Step-by-step explanation:

The exponential distribution of Wendy's service time is given by:

P(x) = [exp (-x/μ)]/μ............................................................................ (1)

P(x) = Probability function

x = Service time, in minute

μ = average service team, in minute, 2.2 minutes

(a) x= 1, substituting into equation (1) we have:

P(1) = [exp (-1/2.2)]/2.2

= 0.6347/2.2

= 0.2885

(b) x₁ = 0.5 minutes

x₂ = 1 minute

P (0.5<x<1) = P(0.5) -P(1) ----------------------------------------------- (2)

From (a), P (1) = 0.2885

P(0.5) =P(1) = [exp (-0.5/2.2)]/2.2

= 0.7967/2.2

= 0.3621

Substituting into (2), we have :

P (0.5<x<1) = 0.3621 -0.2885

= 0.0736

= 0.1030/2.2

= 0.0468

Solve the following: -3x(x-8)+7x=12

Anuta_ua [19.1K]

Step-by-step explanation:

Hello there!

Solve for x:

-3x(x-8)-7x=12

-3x^2+24x-7x=12

-3x^2+17x+12=0

Can you factor it further?Feel free to ask questions in the comments.
